This is weird. I wanted to view Mediawiki:Common.js history but if I go to https://www.mediawiki.org/w/index.php?title=Special:Undelete&target=MediaWiki%3ACommon.js . It gives me an access error. But I already am an administrator here. I get the following message.
The action you have requested is limited to users in the group: Administrators.
Any idea what's happening?
